Influence of the magnetic field on the thermal condensation
P. Hennebelle, T. Passot
The neutral atomic interstellar medium (HI) is well known to be strongly magnetized. Since HI is a 2-phase medium the questions arise of what is the effect of the magnetic field on…
Magnetic Pressure-Density Correlation in Compressible MHD Turbulence
Thierry Passot, Enrique Vazquez-Semadeni
We discuss magnetic pressure and density fluctuations in strongly turbulent isothermal MHD flows in "1+2/3" dimensions. We first consider "simple" nonlinear MHD waves, which allow…
Thermal Instability and Magnetic Pressure in the Turbulent ISM
Enrique Vazquez-Semadeni, Adriana Gazol, Thierry Passot +1
We review recent results on the nonlinear development of thermal instability in the context of the turbulent atomic interstellar medium (ISM). First, we pre- sent a brief summary o…
The Density Probability Distribution Function in Turbulent, Isothermal, Magnetized Flows in Slab Geometry
Enrique Vazquez-Semadeni, Thierry Passot
We investigate the behavior of the magnetic pressure, , in fully turbulent MHD flows in ``1+2/3'' dimensions by means of its effect on the probability density function (PDF) o…
Compressible MHD Turbulence: Implications for Molecular Cloud and Star Formation
E. Vazquez-Semadeni, E. C. Ostriker, T. Passot +2
We review recent results from numerical simulations and related models of MHD turbulence in the interstellar medium (ISM) and in molecular clouds. We discuss the implications of tu…
MHD Turbulence, Cloud Formation and Star Formation in the ISM
E. Vazquez-Semadeni, T. Passot, A. Pouquet
We discuss the role of turbulence in cloud and star formation, as observed in numerical simulations of the interstellar medium. Turbulent compression at the interfaces of colliding…
